Full textAbstract:
The present paper reviews the taxonomic studies of the mite suborder Oribatida in the Russian Far East South and Chinese North-East Territories. At present, 746 species of oribatid mites are registered in China, including 175 species in the soils of Northeast China. In the Russian Far East, there were 605 species of oribatids, including 344 species in the south of the Far East. The fauna of the oribatid mites of the Northeast of China and the south of the Russian Far East has 446 species and subspecies representing 190 genera and 80 families. 72 species of oribatid are common for both territories. The modern fauna of the oribatid mites of the Northeast of China and the south of the Far East was formed as a result of prolonged interaction between the boreal and palaearchaearctic faunas. The oribatid fauna of this region is distinguished by the presence of a large number of endemics, some of which are relics of the late Tertiary time and which can be considered as autochthonous. The checklist includes data from more than 100 locations of this enormous region. In addition, a short climatic and historical review of oribatid mites study is presented.

Oribatid mites (Acari, Oribatida) in selected caves of the Kraków-Wieluń Upland (southern Poland) This paper describes and compares the species composition and community structure of the oribatid mite fauna of 5 caves in the Kraków-Wieluń Upland (Wyżyna Krakowsko-Wieluńska). We also compare oribatid communities in 3 chosen caves with oribatid communities in the soil and litter (leaves, dead wood, bat guano) in the vicinity of the cave entrances. Three hypotheses were tested: (1) oribatid communities from the soil and litter near the caves differ from the communities inhabiting caves; (2) the composition of oribatid communities depends on cave size; (3) the cave communities strongly depend on microhabitat quality and diversity. We collected 1112 adult oribatids from caves and 838 from the soil and litter near the caves. Oribatid communities in the caves were different from the soil communities. Litter, guano and dead wood were the microhabitats that affected oribatid communities significantly. In the other cave microhabitats (soil and mud), oribatids were infrequent. Cave size affected the oribatid community structure.

Full textAbstract:
The fauna of oribatid mites (Acari, Oribatida) in the mountain tundra on the Kola Peninsula (Russia) is still poorly studied. The main aim of this research is to obtain initial data on the fauna and abundance of oribatid mites of the Lovozersky Mountains. We investigated five plots, including three lichen tundra plots, one dwarf shrub tundra plot and one wetted tundra plot in one of the largest mountain massifs of the Kola Peninsula — the Lovozersky Mountains. Multidimensional scaling and discriminant function analysis were used to identify some trends in the fauna and abundance of species on the explored plots. The abundance of oribatid mites in the lichen tundra reached 23,680 ind./m2. In the dwarf shrub tundra, this value is over three times higher — up to 81,160 ind./m2, which is comparable with the oribatid mite abundance of forest habitats. The minimum values were discovered in wetted tundra (6,200 ind./m2). A total of 71 species, 38 genera, and 24 families of oribatid mites were found during the course of this study. Eight species of Oribatida have been added to the fauna of the Kola Peninsula. A significant difference was observed in the structure of oribatid faunas of the explored habitats. The occurrence in samples and relative abundance of Mycobates sarekensis, Oribatula amblyptera, Tectocepheus velatus and Carabodes labyrinthicus increased in lichen tundra compared to dwarf shrub tundra. Species of Suctobelbidae and Oppiidae were higher in occurrence and relative abundance in dwarf shrub tundra compared to lichen tundra. The occurrence and relative abundance of Trimalaconothrus angulatus, T. maior and Platynothrus peltifer prevailed in wetted tundra as compared to automorphic tundra habitats. The family Suctobelbidae was represented by a large number of species, while the family Ceratozetidae showed a small number of species in the discovered fauna. According to the literature, these features of the fauna are unusual for tundra. A low diversity of Ceratozetidae, a high diversity of Suctobelbidae and high abundance of oribatid mites in dwarf shrub tundra may be explained by the ambivalent nature of the oribatid community in the explored region, which combines boreal and arctic features due to marine climate.

Full textAbstract:
The paper considers some features of the web resource "Biodiversity of Ukraine" for the analysis of collections and literature data on the example of oribatid mites of Transcarpathia. Possibilities are investigated for analysis of the spatial distribution of oribatids in terms of georegions of the study area. Their faunal similarity was determined using the Sorensen and Jaccard indexes integrated into the web resource. The territorys have been identified, which are promising for further studies of the fauna and ecology of oribatid mites. The purpose of our work was to test some features of the web resource "Biodiversity of Ukraine" on the example of Transcarpathian oribatids. This approach for the analysis of the diversity of oribatid mites was made for the first time. 273 records representing 129 species of oribatid mites were made for the Transcarpathian lowland. 154 records for 98 species were made for the Vulkanichno-intermountaindells oblast. 507 records for 183 species of oribatids were integrated for Polonynsko-Chornohirska region. 42 finds of 37 species were made for the Marmarosh massive. 114 records of 96 species of oribatids were integrated for the Transcarpathian part of Gorgany massive. It is established that a number of mountain massifs remain completely unexplored in terms of oribatids: Vyhorlat-Hutynskyi, Velykyi Dil, Tupyi and Verkhovynskyi. The latter remains unexplored not only within Transcarpathia but within the entire Verkhovynskyi Watershed range. All these areas are promising in the study of not only taxonomic diversity, but also the ecological characteristics of oribatid mites. The indicators of Sorensen and Jaccard indexes were counted. The value of these indicators depends on the ecological conditions of specific georegions and the degree of studien for oribatid mites. The perspective expediency of using the web-resource "Biodiversity of Ukraine" for comparison of fauna of oribatid mites of different georegions is established. After the integration of more complete information about oribatid mites into the database of the web resource "Biodiversity of Ukraine" it will be expedient to make a faunal comparison of georegions not only of Transcarpathia but also of other territories. The work was performed within the scientific theme: "Estimation of the biotic diversity of model groups of Arthropoda of the Ukrainian Carpathians with the use of modern information technology" (0120U101162).

The objective of this work was to compare the oribatid mite and springtail communities in three plots with different soil use - Coffee (CP), secondary vegetation or fallow fields (acahual, A) and a cloud mountain forest (CMF) - within a coffee plantation located in Santa Maria Huatulco, Oaxaca State, Mexico. In each plot 20 samples (10 of soil, 10 of litter) were taken and processed in Berlese funnels. The extracted fauna was preserved in 70% ethanol. A total of 3,031 oribatid mites belonging to 33 species, and 1,177 specimens of springtails belonging to 43 species, were collected. The number of species recorded was: 27 at CP (14 oribatids; 13 springtails), 44 at A (19 oribatids; 25 springtails) and 62 at CMF (32 for each group). A total of 26 oribatid and 27 springtail species was found in the soil, and 25 oribatid and 32 springtail species were found in the litter. The most abundant species were the oribatids Rostroztes foveolatus (Haplozetidae), Tectocepheus sp. (Tecocepheidae), Karenella sp. (Oppidae), Atropacarus (Hoplophorella) cf. fonseciai (Phthiracaridae), Epilohmannia pallida americana (Epilohmannidae), and the springtails Ceratophysella cf. gibbosa (Hypogastruridae), Mesaphorura sp. (Tullbergidae) and Proisotoma cf. minuta (Isotomidae). Fourteen families and 18 species of Oribatida species and 5 families and 34 species of Collembola were recorded for the first time for the State.

AbstractOribatid fauna highly varies among habitats, but different microhabitats within a habitat are also characterized by different mite species. The main goal of the research was to compare the observed structure of an oribatid community when samples were collected at random from the soil-litter layer of 0-10 cm in depth (standard approach) and selectively from 6 types of available microhabitats (complex approach). Samples were taken within a small plot (10 m × 10 m) in a forested area of the Silesian Park (Chorzów, south Poland). Overall, 2642 specimens of Oribatida belonging to 62 species were collected in 66 samples. The structure of the oribatid community observed by means of the 2 sampling approaches was completely different. The abundance and species richness of oribatid mites collected from 6 microhabitats were significantly higher than in the soil-litter layer alone. Results of this study show that random collecting of only soil-litter samples may reduce the evaluation of species richness in a study area by 40%. Each of the studied microhabitats supported a peculiar oribatid fauna.

Comparison of Earthworms (Lumbricidae) and Oribatid Mite (Acari, Oribatida) Communities in Natural and Urban Ecosystems This study investigates earthworm and oribatid mite communities in urban, semi-natural and natural ecosystems of Tbilisi (Georgia). Ten species of earthworms and 100 species of oribatid mites were registered in 45 soil samples. Two species of oribatid mites, Microzetes auxilaris Grandjean, 1936 and Multioppia laniseta Moritz, 1966, are new for the Caucasian fauna. We hypothesized that species number and abundance of invertebrate animals tend to decrease from natural to urban ecosystems. The hypothesis was supported only partially. Number of species of oribatid mites and earthworms decreased together with increase of urbanization, whereas abundance showed no significant changes due to high density of stress tolerant and ubiquitous species in urban sites. Accordingly, species abundance is considered to have minor indicatory value. Our studies support ecological "time-hypothesis" in a way that older (natural) sites were presented with more diverse fauna than recent (urban) ones. Statistical analyses showed that studied ecosystems should be grouped in two rather than three categories: in urban and natural ones.

Species composition and abundance of the oribatid fauna (Acari, Oribatida) at two lakes in the Fløyen area, Bergen, Norway Oribatid communities from the edges of two lakes in the Fløyen area, Bergen, Norway, were compared in June 2005. The lower lake, Blåmansvannet (412 m a.s.l.), is surrounded by spruce forest, while the ‘Higher Lake’ (513 m a.s.l.), is above the tree line. Both lakes have a low pH and their edges are dominated by Sphagnum mosses. The abundance of total mites, as well as of Oribatida, were almost 2-fold higher at the ‘Higher Lake’ (51 510 and 51 160 ind./m2, respectively), while species diversity was lower than at Blåmansvannet. On the shore of Blåmansvannet, the eudominant (20% < D ≤ 40%) species was Trimalaconothrus maior, while Liochthonius peduncularis, Limnozetes ciliatus, and Nanhermannia cf. coronata were dominant (10%< D ≤ 20%). At ‘Higher Lake’, the eudominant species was Limnozetes ciliatus, which reached a 4-fold higher abundance (15 930 ind./m2) than at Blåmansvannet, and dominant species were Liochthonius alpestris, Nanhermannia cf. coronata, and Platynothrus punctatus. At both lakes, juveniles made up about 30% of all oribatids. Four species are new to Norway: Ceratoppia sexpilosa, Liochthonius alpestris, Liochthonius peduncularis, and Trhypochthoniellus longisetus.

Influence of sewage sludge composts with straw or ash on oribatid mites (Acari, Oribatida) from pine forest litter in laboratory conditionsIn a substrate obtained from municipal sewage sludge composts, the C:N ratio was decreased during the 12-month experiment. The amount of forest litter (layer 1 or 2 cm thick), used for fauna introduction, did not influence significantly the mean abundance of oribatid mites in sewage sludge compost. Oribatid mites tolerated compost alone or with straw, but were negatively influenced by addition of wood-ash. Abundance of oribatid mites in compost alone was increased from the 3rdmonth, and its maximum occurred in the 10thmonth. Abundance of oribatid mites in compost with straw was clearly increased since the 10th-12thmonth of the experiment. Generally the abundance of oribatid mites was mainly affected byRamusella mihelcici, which was most abundant in compost alone and with straw (maximum abundance was above 100 000 individuals · m-2). However, species diversity of the mites was very low at the end of the experiment.

Fauna and ecological diversity of oribatid mites of hygrophyte grasslands on Transcarpathian lowland is considered in the paper. For Transcarpathia, such studies have not been conducted before. For hygrophyte grasslands 45 species of Oribatida (25 families, 34 families) are registered. The most numerous among detected taxa were Platynothrus peltifer, Ceratozetes mediocris and Oppiella nova. It has been established that dominant role belongs to the surface-soil morpho-ecological group of oribatid mites. In the ecological structure, predominant role is inherent of hydrophilous and eurytopic species.

Full textAbstract:
This study examines the short-term impact of forest soil compaction and organic matter removal on soil mesofauna, in general, and oribatid mite species, in particular. Both soil compaction and organic matter removal reduced the density of soil mesofauna. Stem-only harvesting reduced total mesofauna densities by 20% relative to uncut forest values. A combination of whole-tree harvest and forest floor removal with heavy soil compaction significantly reduced total soil mesofauna densities by 93% relative to the uncut forest control. Removal of the forest floor represents a substantial loss of habitat for most soil mesofauna. The forest floor apparently buffered the mineral soil by limiting both the impact of soil compaction and fluctuations in soil temperature and moisture. The relative abundance of Prostigmata and Mesostigmata increased with treatment severity, whereas that of Oribatida decreased. Species richness of the oribatid mite fauna was reduced as the severity of treatments increased. The number of rare oribatid species (those representing <1% of the total oribatid mite sample) decreased by 40% or more relative to the uncut forest control. Evenness also decreased as treatment severity increased. Oppiella nova and Suctobelbella sp. near acutidens were the dominant oribatid species in both the forest floor and mineral soil, regardless of treatment. Soil compaction and organic matter removal significantly impacted the density and diversity of soil mesofauna and oribatid mite fauna in the short term at these study sites.

Full textAbstract:
A checklist of the oribatid mite species reported in Brazil is presented, including all published records up to 2015. A total of 576 described species in 206 genera and 83 families is presented. Information includes the names by which each species was reported in the Brazilian literature, its general known distribution and by Brazilian States, references, and remarks, when needed. As with most countries, there was a slow early accumulation of knowledge but in recent decades the pace of description has been relatively high. A graphical overview of the number of described oribatid mite species from Brazil in different decades is given. The proportion contributed by each of the major oribatid groups is generally similar to that of the overall world fauna, with a composition that reflects the South American fauna and all of the Neotropics in general. There is a relatively low percentage of primitive mites (Palaeosomata, Enarthronota) other than Lohmanniidae and Mesoplophoridae, which are quite diverse. The Brachypylina comprises about 68% of the oribatid mite fauna. In the checklist, 41% of the species are known only from Brazil, 37% from the Neotropical region, 13.5% have a wider distribution in the global tropical and subtropical regions, and 8.5% are considered cosmopolitan or semicosmopolitan species. The number of descriptions of new species since 2000 from Brazil (73 spp.) and South America (230) is high, but the oribatid mite fauna of these countries remains poorly known. Only continued studies can determine if the high number of species known only from Brazil is an indication of high endemism.

We analysed the community of oribatid mites in 25 environments of northern Brazil and one in a rain forest in Peru, encompassing fauna sampled on natural and artificial (nylon-mesh bags) substrata, from primary and secondary forests, caatinga, savannahs, flooded forests, bark and epiphytes of trees, and polyculture. A hundred and forty six species are definitively identified from a total of 444 taxa. To determine changes in the community, we took as a basis of comparison the species dominance of Lower Oribatida vs. Oppioidea and Lower Oribatida vs. Poronota. Even considering the different periods in which the inventories were realized and the different sampling methodology compared, the partition of the species of Oribatid mite in larger groups shows tendencies indicating partition of species dominance among the environments studied, showing that they differed in their suitability as habitats for the Oribatid mite community, mainly in respect to the Lower Oribatida, Oppioidea and Poronota composition. These tendencies should be explored in more detail as more becomes known about the species composition in each environment.

Full textAbstract:
The aim of this research was to obtain initial data on the fauna and abundance of the oribatid mites from the main types of the mountain tundra habitats of the Chunatundra Mountains. Four plots, including two lichen tundra plots, one dwarf shrub tundra plot and one sphagnum bog in the belt of mountain tundra were investigated. Multidimensional scaling and discriminant function analysis were used to identify trends in the fauna and abundance of oribatid species through the explored plots. A total of 70 species and one subspecies from 37 genera and 24 families were found during the course of this investigation. Nine species, one subspecies, one genus and one family of oribatid mites have been added to the fauna of the Kola Peninsula. The families Brachychthoniidae, Oppiidae and Suctobelbidae are the most diverse in the discovered local fauna. According to literature data, the first two families are characteristic of the low tundra communities, the third family is more common for the boreal zone. The discovered oribatid fauna is similar to the fauna of other tundra sites of the Kola Peninsula studied previously and is significantly different to the local oribatid mite faunae of the Scandinavian Peninsula. The abundance of the adult oribatid mites reached 39 080 ind./m2 in the lichen tundra and 56 200 ind./m2 in the dwarf shrub tundra. The minimum abundance of oribatid mites, 18 640 ind./m2 was found in the sphagnum bog. Differences in the oribatid mite complexes of lichen tundra, dwarf shrub tundra and the sphagnum bog were found. The species Carabodes labyrinthicus, Nothrus borussicus, Sellnickochthonius immaculatus, Mycobates sarekensis, and Tectocepheus velatus were associated with the lichen tundra habitats. Nanhermannia sellnicki, Chamobates borealis and a few species of Oppiella and Suctobelbella were associated with the dwarf shrub tundra. Mucronothrus nasalis, Limnozetes ciliatus, Platynothrus peltifer, Trimalaconothrus foveolatus, Limnozetes cf. rugosus, and Trimalaconothrus maior are most characteristic of the sphagnum bog. The family Suctobelbidae was represented by a large number of species, while the families Ceratozetidae and Camisiidae were much less diverse. The low diversity of Ceratozetidae, a high diversity of Suctobelbidae and relatively high abundance of oribatid mites in the explored tundra habitats may be explained by an ambivalent nature of the oribatid community, which combines boreal and arctic features due to marine climate. Also, this result may be a feature of a local mountain tundra which is surrounded by the underlying belts of the mountain forests that are a source of the increasingly diversity of species.

Oribatid mites (Acari, Oribatida) and their seasonal dynamics in a floating bog mat in Jeziorka Kozie Reserve, Tuchola Forest (Poland) The oribatid mite community from the edge of the Sphagnum mat of dystrophic K1 pond (Jeziorka Kozie Reserve, Poland), and its seasonal dynamics was studied in 2006 (29 May, 6 August and 22 October). In all seasons, Limnozetes foveolatus dominated, followed by L. ciliatus; abundant were also L. lustrum, Trhypochthoniellus longisetus, Trhypochthonius nigricans, and Trimalaconothrus foveolatus. In autumn, the mean density of Oribatida was significantly higher than in spring. The percentage of juvenile stages was generally low, but highest in summer (22%), while in the other seasons it was about half as high. Metabelba sphagni is new to the Polish fauna.

Full textAbstract:
A checklist of the oribatid mite species from two boreal fens in Northern Ontario, Canada is presented. 174 peat soil samples, collected between 2015–2020, yielded a heterogeneous assemblage of 80 species, 57 genera and 33 families. Species richness and diversity were significantly higher in a Sphagnum-dominated fen (69 species) compared to a Carex-dominated fen (51 species), and although 40 species were found at both sites, overall composition was significantly different between the two sites. We also present an update to the seminal work of Behan-Pelletier and Bissett (1994) on Oribatida of Canadian peatlands with 45 new species records for peatlands. Records for the parthenogenetic families Brachychthoniidae Thor, 1934 and Suctobelbidae Jacot, 1938 were considerably expanded, but other families such as Punctoribatidae, Thor, 1937 remain poorly represented in Canadian peatlands. Taken together, species richness estimates range from 86–105 species based on our sampling and the number of undescribed species recorded suggests that the oribatid mite fauna still need further examination to encompass their actual biodiversity in peatlands.

Full textAbstract:
This paper presents a catalogue of oribatid mites (Acari, Oribatida) recorded from Continental Southeast Asia (CSEA) covering a period of 55 years from 1965 to the first half of 2020. This subregion comprises countries that are located on the southeastern coast of the Asian continent, namely, Myanmar, Thailand, Laos, Cambodia and Vietnam. For each species, information is compiled on references to the original description, subsequent re-combinations of specific name with other genera, and junior synonyms used in CSEA literature, if any, as well as type habitat, habitats recorded later, and distribution within outside CSEA. A historical review of explorations and taxonomic studies in the various countries is also provided. A total of 820 valid species including subspecies and seven doubtful species are known so far from CSEA. The valid species belong to 313 genera and subgenera, 94 families and 36 superfamilies in all of the five infraorders and two hyporders of the Suborder Oribatida. The Hyporder Brachypylina is most diverse with 620 species, followed by Mixonomata (88), Enarthronota (65), Nothrina (41), Palaeosomata (5) and Parhyposomata (1). Vietnam whose fauna has been best explored tops the records with 730 species, followed by a low second by Thailand (137), then Cambodia (37) and Myanmar (11) while the oribatid fauna of Laos is still entirely unknown. Altogether, the oribatid fauna of Southeast Asia (SEA), including its two subregions, now totals 1601 species belonging to 477 genera, 109 families and 40 superfamilies. Species that are known so far only from CSEA countries and thus probably endemic is highest at 36.4% for Myanmar, 32,1% for Thailand, 23.7% for Vietnam, 0 for Cambodia, 27.2% for CSEA, 59.0% for the Malay Archipelago, and 48.7% for SEA as a whole. About 7% of the recorded species of Thailand and Vietnam are cosmopolitan or semicosmopolitan in distribution, but their faunal elements are decidedly Oriental, with about half (43–54%) occurring also in other Oriental countries. The same countries also share in common many species with other zoogeographic regions, viz. 12–14% Palaearctic, 8–16% Australian, 8–11% Neotropical, 3–11% Ethiopian, and 1–3% Nearctic.

Abstract The present publication provides a review of the soil mite (Acari; Oribatida) community’s structure and the connection between changes in environmental factors and oribatid mite diversity in the limestone quarry of Saskhori and its adjacent areas. Overall, 52 species were recorded during the study. The most abundant oribatid mite species were Steganacarus carinatus, Aleurodamaeus setosus, Xenillus tegeocranus, Ceratoppia bipilis, Oribatula tibialis, and Punctoribates punctum. Interestingly, 23 species of oribatid mites were recorded for the first time from the limestone quarry of Saskhori, and one species (Liacarus oribatelloides) was a new record for the Caucasus fauna. The following indices were analyzed: abundance (N), species diversity (S), Shannon’s diversity index (H), and Pielou’s evenness index (J’). Regarding the obtained results, the highest density of oribatid mites was recorded in the habitat with Shibliak shrubbery (332 inds/m2), while the forest habitat was characterized with the highest value for Shannon’s diversity index (2,64). In the publication, we also provide a detailed morphological description of the newly recorded species L. oribatelloides, with the respective illustration, as no figures are given in its original description.

The purpose of this work is to publish new data on the species composition of oribatid mites in the North Caucasus, which will make possible to clarify the destribution of the oribatids of the world fauna region. The material was collected in 2003-2009, according to generally accepted methods, in 23 habitats in the territory of Adygea, Dagestan, Kabardino-Balkaria and the Krasnodar Territory in various altitudinal levels: in alpine and subalpine meadows, in mountain forests of various types (birch, pine, beech or mixed), mesophytic meadows in the forest zone, in xerophytic shrubs and mountain steppes, floodplain meadows and salt marshes of the semidesert biotopes of the lowland zone. Results. There were found 349 species of the oribatid mites from 158 genera and subgenera belonging to 62 families. Forest habitats are characterized by the greatest species diversity, there are found 232 species of oribatids. In the alpine and subalpine meadows 158 species are noted, 71 species are found in the mountain steppe zone, 47 species in the salt marshes of the semidesert zone, and 7 species in the floodplain meadows. For the first time in the Caucasian region one genus Novosuctobelba Hammer, 1977 and 29 species of the oribatid mites are registered, founded earlier only in Japan, China, Somalia and some countries of the Mediterranean. There are 14 new taxa for science: 12 species and 2 subspecies. Conclusion. In 23 biotopes of 18 geographical points of the Northern Caucasus 349 species of the oribatid mites from 158 genera and subgenus and 62 families were found. The number of species found in the biotopes of different altitude zones corresponds to the basic patterns of distribution of oribatids in mountain ecosystems: the biotopes of the forest zone are characterized by the greatest species diversity, the number of species in the soils of alpine and subalpine meadows and biotopes of the mountain-steppe zone is somewhat lower, the smallest number of species is found in the semidesert zone. For the first time in the Caucasian region one genus and 29 species of oribatid have been recorded, which allows to expand the areology of some species of the oribatid mites. There are 14 new taxa for science.

Full textAbstract:
AbstractThis paper reviews and summarizes preliminary data on the taxonomy, distribution, and ecology of oribatid mites of Canadian peatlands, primarily those of eastern Canada. This fauna is a heterogenous assemblage comprising 71 species in 49 genera and 34 families, found in four main types of habitats: aquatic, mesic, xeric, and epigeal. About half of the oribatid fauna of peatlands, and most aquatic species, are restricted in distribution to the Nearctic. Oribatid taxa known or suspected to be parthenogenetic are much better represented in peatlands than in the general Canadian fauna. Data on the feeding habits of odonate larvae in Newfoundland bog pools, based on gut content analysis, show that oribatid mites, in particular species of Limnozetes Hull and Hydrozetes Berlese, are common prey of species of Aeshna Fabricius, Leucorrhina Brittinger, and Libellula L. A synopsis of available data suggests that assemblages of Limnozetes species may be useful in characterizing peatlands.

This checklist of the oribatid fauna of Canada and Alaska (excluding Astigmata) includes 580 identified species in 249 genera and 96 families. The known fauna of Canada includes 556 identified species in 247 genera, and that of Alaska includes 182 species in 95 genera; 39 of the 42 oribatid superfamilies are represented. We further list ~ 300 species that are currently unidentified, and possibly undescribed. In addition, we list 42 genera that are represented only by unidentified and probably undescribed species. For each species we give combinations and synonymies, specific locations in Alaska and the Provinces and Territories of Canada, habitats, and biogeography. There are 182 identified species known for Alaska, 152 for Yukon, 122 for Northwest Territories, 58 for Nunavut; 210 for British Columbia, 213 for Alberta, 15 for Saskatchewan, 84 for Manitoba, 167 for Ontario, 210 for Québec, 110 for Nova Scotia, 77 for New Brunswick, 84 for Newfoundland and 6 for Prince Edward Island. The known fauna of Canada is smaller than that of Austria, and is approximately equivalent to that of the Czech Republic. As these countries are much smaller in size than Canada and less ecologically diverse, we consider the Canadian and Alaskan fauna are at most 25% known. The paucity of these data reflects the absence of taxonomic and faunistic studies on Oribatida in State, Provinces or Territories, and especially in the Canadian and Alaskan National Park systems and the hundreds of Provincial Parks. Despite the almost 90% increase in described species since the catalogue of Marshall et al. (1987), there is a need for focussed, coordinated research on Oribatida in the natural regions throughout Canada and Alaska, and for monographs on families and genera with large numbers of undescribed species, such as Brachychthoniidae, Damaeidae, Cepheidae, Liacaridae, Oppiidae, Suctobelbidae, Hydrozetidae, Phenopelopidae, Scheloribatidae, Haplozetidae and Galumnidae.

Forest sites in Northwestern Argentinean Patagonia were surveyed to determine the oribatid mite fauna. A taxonomic inventory of oribatid mites was carried out in Northwestern Argentinean Patagonia to establish the taxonomic diversity, for increasing the knowledge of their distribution, detecting new species and assessing environmental effects on the oribatid mite community. Eleven sampling sites in nearly pure forests of Austrocedrus chilensis, Nothofagus dombeyi, Nothofagus antarctica were selected as these are among the most recurrent arboreal species found in this region. Samples of leaf litter, soil and pitfall traps contents were taken from each forest. Fifty-five oribatid species, belonging to 46 genera in 28 families, were found. Nine species are new records for Argentina and one for continental Argentina. Thirty-two species were recorded in A. chilensis forests, 35 in N. dombeyi forests and 20 in N. antarctica forests. Fifty species were found in leaf litter, 35 in soil and eight in pitfall traps. Fourteen species were recorded exclusively in leaf litter, one in soil and four in pitfall traps. A high level of endemism is confirmed as nearly 62 % of collected species have previously been found only in Southern Andes supporting the existence of an associated autochthonous oribatid fauna.

Full textAbstract:
The aim of the study was to assess the impact of several methods of mulching degraded forest soil with wood chips on the development of mite (Acari) community, with particular emphasis to oribatid mites (Oribatida), and on the growth of young plantings of Scots pine (Pinus sylvestris L.). Mulching with wood chips should contribute to revitalize soil fauna and restore natural forests on degraded soils. Scots pine seedlings were planted at the post-military training ground. Four experimental treatments were tested: control—uncovered soil (C), mulching with wood chips (W), W + mycorrhiza preparation (WM), and W + forest litter (WL). At the end of the growing season in 2012, 2013 and 2014, the following plant measurements were carried out: length of annual increment of the main stem, stem base diameter, number and lengths of lateral shoots in the annual whorl. The mite calculations included average mite density, dominance index, species richness, oribatid mite diversity, average number of species, and Shannon general species diversity index. The use of mulching with wood chips did not significantly affect the growth characteristics of Scots pine plants, but strongly increased the mite community. After mulching, the total number and species diversity of Acari increased many times, and Oribatida began to dominate among micro-arthropods. The number of Oribatida increased most in W. The largest species diversity was observed in WL. 24 species of Oribatida were found that were used as the bio-indicators of soil succession changes. Tectocepheus velatus clearly dominated in all mulching treatments. Oppiella nova and Scutovertex sculptus were also numerous populations of Oribatida. The study shows that mulching with Scots pine wood chips, especially with the addition of forest litter, significantly enriches soil fauna and is therefore useful in the regeneration process of degenerated forest soils.

Full textAbstract:
New Zealand’s soil biota is diverse and unusual, and has high levels of species endemism. Soil microarthropods are the major (and least studied) part of NZ land fauna, yet changes in their biodiversity are often difficult to quantify, because the baseline data are lacking. Data on alpine fauna and flora are a priority in preserving NZ biological heritage, as they are vulnerable to range contraction and higher-altitude displacement due to climate warming. In this presentation we briefly summarize the gaps and challenges in our knowledge of NZ alpine invertebrate biodiversity. The patterns in diversity and community structure of soil Oribatida in the alpine zone vs. upland forests are discussed using spatially-explicit data from several alpine regions of the South Island. Focusing on environmental and spatial analysis, we answer several questions: 1) is alpine plant diversity a significant driver for oribatid species diversity in the high alpine, and if not, what is? 2) Did limited dispersal and habitat fragmentation during Pliocene mountain building and Pleistocene glaciation produce regionally unique alpine communities, or is the alpine fauna a generic depauperate fragment of communities below treeline? 3) What is the scale of species turnover patterns across the alpine landscape? There is also an interesting opportunity to compare oribatid communities of alpine New Zealand with those bearing similar ecophysiological challenges in the Northern Hemisphere.

Knowledge of the oribatid mite community from Patagonian steppe is scarce compared with other environments, such as the Andean-Patagonian forest. In the present research we identified oribatid mites under different environmental conditions: two Patagonian steppe types (grass and shrub), two soil characteristics (bare and covered soil) and two different seasons (autumn and spring). A total of 42 species/morphospecies were found, 13 were new records for Chubut and one was a new record for Argentina. In view of its ecological role in soil formation, it is fundamental that knowledge about this fauna is enhanced in order to provide baselines for study and to aid further understanding about its ecology.

Importance of tree hollows for biodiversity of mites (Acari) in the forest reserve "Śrubita" (Carpathian Mountains, south Poland)Tree hollows harbour a specialized fauna, and mites usually are the most numerous arthropods in this microhabitat. Mite fauna in 3 types of tree hollows was studied in the forest reserve "Śrubita" near Żywiec, at an altitude of about 850 m. In total, 2037 individuals of Acari and 1414 of Oribatida, representing 72 species, were collected. Over 1200 individuals per 100 g dry weight of wood dust were collected from tree hollows. The total number of oribatid species in tree hollows was higher than in the forest floor. Most species (also dominants) were obligate members of communities of a certain type of tree hollows.

Urban brownfields are ecologically valuable ecosystems that have been and are under various anthropogenic influences. Because brownfields are subject to rapid development in urban areas, their biological communities, including soil mesofauna, are overlooked and seldom researched, even though they could provide valuable insight into the ecological functioning of these areas. This exploratory study describes the community characteristics of oribatid mite fauna of 12 brownfields in Tallinn, Estonia, and analyzes the potential of oribatid mites as bioindicators of brownfield successional stage. This study provides the first faunistic list of oribatid mites from the brownfields of Tallinn. No significant changes in species abundance or richness depending on the successional stage were discovered. While some changes in community structure were noted, due to low overall abundance, no clear indicators of brownfield successional stage were identified. For future research on urban brownfield oribatid fauna with the intention of finding potential bioindicators of brownfield properties, increasing the sampling size and inclusion of other groups of soil mesofauna is recommended.

The “MGP analysis” created by Dr. J. Aoki in 1983 and the “100 oribatid species” system proposed by Aoki in 1995, both for using oribatid communities as bioindicators, are described herein and compared to some other bioindicator protocols. By using the term “naturalness”, Aoki proposed to explain human impact on a gradient of several environments ranging from urban boulevard trees to intact forests.Although using “naturalness” was a vague concept, the idea might reflect the process of plant succession and changes in oribatid assemblages associated with different seral stages. Therefore, the use of oribatid mites as bioindicators might also be based on succession of the oribatid fauna.

The article is a synthesis of the studies on oribatid mites carried out in Vietnam during the period of 1980-2013, and is based on the oribatid materials obtained throughout the country. The oribatid mite fauna (Acari: Oribatida) of Vietnam is diversified, and has high specialization. It is diverse by the number of superfamilies, families, genera and species recorded. However, the number of genera per family, as well as the number of species and subspecies per genus, is not high. 43.75% and 37.50% of the total 64 families and subfamilies consist of one and of 2-3 genera, respectively. The only one family Oppiidae Grandjean, 1954 consists of 23 genera. The majority of the genera, 68.10% of the total, are represented by one species. The only two genera are represented by more than 10 species, namely Galumna Heyden, 1826 and Pergalumna Grandjean, 1936, with 13 and 11 species, respectively. The main zoogeographical characteristics of the oribatid mite fauna of Vietnam are the Oriental species, representing 60.30% of the total number. It also includes the elements of the Palaearctic – Oriental (12.2%), the Cosmopolitan (10.6%), the Afrotropical (Ethiopical) – Oriental (6.9%), the Australian – Oriental (5.0%), the Neotropical – Oriental (3.8%), the Nearctic – Oriental (0.9%), and the Pacific - Oriental (0.3%).

<p>In the successional recovery processes of quarry-spoiled systems soil-living oribatide mites, who are one of the pioneer groups inhabiting anthropogenically transformed areas, play a significant role. The aim of our study was to research composition and characteristics of oribatide mites ecological community structure of the ‘Osnovnoy’ quarry (PJSC ‘HeidelbergCement Ukraine’) in Amvrosievsky district of Donetsk region.</p> <p>The material was collected in 2012. In total, 37 standard soil samples of 250 cm<sup>3</sup> were collected, from which 1086 adult specimen, who belong to 61 species, were extracted in April. The collection of soil samples and forcing of oribatides in thermoelectors was conducted by the conventional method of E. M. Bulanovа-Zahvatkinа. To analyze the communities domination structure the gradations of dominance by the means of G. Engelmann scale was used.

AbstractThe archipelago of Svalbard in the European High Arctic lies on the convergence of the Palaearctic and Nearctic flora and fauna and contains elements of both regions. The island of Hopen is located in the south east of the archipelago within the path of the cold south−westerly flowing East Svalbard Current originating in the Arctic ocean and flowing along the north Russian coast. This current is postulated as a colonization route of the invertebrate fauna of Svalbard. Few reports of the terrestrial invertebrates of Hopen exist and none of the mite suborders Oribatida or Mesostigmata. With the taxonomic confusion existing in the inventories of this important region of the Arctic, new sampling campaigns with species identified by modern taxonomic principles and with material deposited in accessible museums and collections are essential. Identified mites included six species of oribatid mites with Diapterobates notatus dominating, and five species of Mesostigmata with Zercon forsslundi forming the dominant species. None of the species collected was a new record for Svalbard and all have wide circumpolar, Palaearctic or Holarctic distributions. Dispersal to Svalbard from northern Russia is hence neither supported nor rejected. The expected oribatid and mesostigmatid diversity of the island is greater than observed from the limited sampling described here.

AbstractIn a pioneer application of acarology to Quaternary fossil-bearing sediments in southern Africa, the oribatid composition in the Florisbad Quaternary sediments was determined and compared to the currently known distribution of those species. Nine species of oribatid mites were recorded in the Holocene aeolian deposits of the third test pit, three species from the Middle Stone Age (MSA) horizon sediments of the third test pit, and thirteen species from the Holocene spring sediments. The Florisbad results indicate a better agreement between the oribatid fauna of the last interglacial MSA horizon of the third test pit and the organic-rich mid-Holocene deposits near the spring than between either of these and early- and late-Holocene aeolian sediments of the third test pit, suggesting some similarity in microsedimentary environments. The majority of the species recorded in the sediments are parthenogenetic and can be regarded as pioneer species.

Full textAbstract:
The mesovoid shallow substratum (MSS) is a unique habitat that shelters and serves as a microrefuge for epigean, endogean and hypogean invertebrate species. Understanding the MSS community′s spatio-temporal structure and species diversity patterns in relation to the environmental parameters plays a crucial role in conservation. In this study we investigated: i) the diversity and community structure of oribatid mites from edaphic habitat, superficial MSS (i.e., the upper layer of MSS) and deep MSS (i.e., lower layer of MSS) in an alpine region of Southern Carpathians, Romania, and ii) the relationships between the oribatid mite communities and the environmental variables, such as temperature and humidity. The composition and the structure of oribatid communities differed along the three habitats indicating possible habitat specialization. The structure of the oribatid community was influenced by temperature and humidity. The rich and mixed oribatid communities in the MSS and the oribatid communities' response to surface and subsurface environmental variables suggest that the MSS may offer a micro-refuge for edaphic species when the conditions in the surface habitats become too harsh. Thus, we suggest that MSS should be prioritized for conservation because it may be the key component in maintaining biodiversity.

This study presents data on the oribatid mite fauna of the Subpolar Urals for the first time. Observations were made in the Lembekoyu River valley and 35 species of oribatid mites from 24 genera and 21 families were found. The analysis of taxonomic diversity and distribution of East European tundra oribatid mite species is presented based on available literature and the author’s own research findings. The taxonomic list includes 163 species from 81 genera and 45 families. Ceratozetidae (15 species), Crotoniidae (14 species), Oppiidae (12 species), Suctobelbidae (12 species), Damaeidae (9 species), Brachychthoniidae (8 species), Phthiracaridae (5 species), Humerobatidae (5 species), Achipteriidae (5 species), Punctoribatidae (5 species), and Galumnidae (5 species) are the leading families, comprising more than 58% of all species. The zoogeographical structure of the fauna is dominated by widely distributed Holarctic, cosmopolitan, and semi-cosmopolitan species. The share of Palaearctic species is 23%. The specificity of the fauna of East European tundra manifests itself in the small group of Arctic species, both in the mainland tundra and on the Arctic islands. A complex of arctic-boreal species, widely distributed in the Eurasian sector of the Arctic, is distinguished.

Full textAbstract:
Abstract Prescribed burning is used to maintain and restore habitats, to protect and increase species bio-diversity. Knowledge about soil fauna is limited, especially on community responses to fire disturbances. The aim of this study was to determine the immediate effects of prescribed burning on soil armoured mite (Acari: Oribatida) communities, vegetation cover and soil physiochemical properties in a boreal Scots pine forest in Latvia. Soil samples were collected on the day of the prescribed burning in the protected landscape area “Ādaži” and 16 days after. No significant changes in abiotic factors were found. Fire significantly decreased the vegetation cover. After the burning, the total number of oribatid mites decreased by 93%, and the number of species by 77%. Changes in oribatid mite communities were significantly influenced by fire severity. The number of individuals decreased among all taxa, except Brachychthonioidea spp. and Cosmochthonius lanathus. A significant decrease in abundance was observed in previously abundant species — Suctobelbella spp., Oppiella nova and Tectocepheus velatus. After the burning, Suctobelbella spp. was an eudominant and Tectocepheus spp. was a dominant genus.

Full textAbstract:
We studied responses of Acari, especially oribatid mites, to prescribed low-intensity fire in an east side pine site in the southern Cascade Range in California. We compared oribatid population and assemblage responses to prescribed fire in stands that had been selectively logged to enhance old growth characteristics, in logged stands to minimize old growth characteristics, and in undisturbed forest reference stands. Low-intensity prescribed fire altered habitat characteristics within the organic layer of forest soil. Acarine populations declined following prescribed fire, and oribatid losses accounted for two thirds of that decline. Individual oribatid species responded differently to prescribed fire, with a few populations increasing after fire but most declining. The prescribed fire also altered oribatid assemblages, reducing species richness and species diversity and modifying assemblage dominance relationships. We also identified several oribatid taxa that were potential indicator species of fire effects upon forest soil fauna. Finally, our results suggested that oribatid responses to fire were intensified by stand alteration and especially by removal of old growth structural characteristics. Decline in oribatid abundance, species richness and diversity, and loss of equilibrium dominance relationships was greatest in the low structural diversity plots.
